Can you just leave money in your paypal account? Paypal sent me $$ as part of a promotional program when purchasing on-line. I received an e-mail telling me it was there, but haven't done anything with it because I've only ever sent with paypal, never received. My thought was that the next time I need to send money, I'll have a little nest-egg there to start with. Am I right, or is it move it or lose it?
